You can also do this by passing function with onclick event   lt a onclick  getColor this    color  red  gt    lt script type  text javascript  gt   function getColor el         color     el  attr  color         alert color       lt  script gt

You need some form of iteration here  as val  except when called with a function  only works on the first element      input placeholder    val    input placeholder    attr  placeholder       should be      input placeholder    each  function            this  val    this  attr  placeholder            or      input placeholder    val function         return   this  attr  placeholder
